The books were also available for sale in Italy and France, where penalties are imposed for denying the Holocaust.

Other anti-Semitic texts, such as a book claiming that the German Weimar Republic, which preceded the rise of the Nazis, was controlled by Jews, and another comparing Jews to devil worshipers, are also available through Amazon.

The books were removed from the online store in countries where Holocaust denial is illegal after Amazon was contacted by The Sunday Times, but they remain available in the United Kingdom, where there are no such legal restrictions.

Many of the books on the site have received low ratings with scathing comments, but others got four star reviews and have been praised as shedding light on the “truth.”

Gideon Falter, chairman of the Campaign Against Anti-Semitism, told The Independent: “Every day, Amazon promotes a selection of literature advocating Holocaust denial and Jew hatred. Anybody searching Amazon for books about the Holocaust, including children working on school projects, will inevitably be shown Amazon’s squalid cesspool of neo-Nazi titles. Amazon’s conditions prohibit the sale of ‘offensive material’ but these titles are ‘dispatched and sold by Amazon’. Amazon is profiting from the trade in titles promoting Holocaust denial and anti-Semitic conspiracy myths.”

Amazon has not made any comment about the controversy, nor has it explained why the company removed the books from certain European websites.
